Conceptual, Schematic and Design Development
Planning, Design, Construction, & Operation
Objective:
Model all sustainable aspects of a project throughout its life-cycle in order to obtain the desired LEED certification in the most efficient manner by condensing design analyses into a single database. Sustainability Criteria Analysis is defined as a process in which all sustainable aspects and features of a building are tracked in order to obtain the desired sustainable certification by condensing various criteria analyses into a single database.
Description:
The primary focus of Building Information Modeling and Sustainability alike is to maximize efficiency while eliminating waste. This can refer to materials, performance, or a process. Sustainability Evaluations can be applied across all four phases of a construction project, Planning, Design, Construction, and Operation. BIM and Sustainability go hand in hand in transforming construction industry nowadays and both affect every phase of a construction project. Sustainability evaluation is most effective when it is done in planning and design stages and then applied in construction and operations phase.
Planning
BIM Applications can be used at this phase for evaluating Site Selection and Spatial Planning. A major concern for LEED projects is the proper use of daylight.The sun is valuable for lighting and heating considering that it provides an abundance of energy at no cost. How this resource can be utilized greatly affects a building's energy consumption. Creating a preliminary BIM allows planners to properly orient the building on the site and the spaces within that building so that the usage of natural light can be maximized.
Design
Nearly a third of the LEED credits for a project are concerned with atmosphere created inside and the impact the building's system has on it. Since buildings consume 40% of the world's energy, this primarily concerns the systems with the highest demands, electrical and mechanical. Several BIM programs allow the designer to create energy models in which an Energy Analysis, Lighting Analysis, or HVAC Analysis can be performed to predict what the different consumptions of each system will be. This is an improved method from traditional hand calculations.
Construction
Currently, BIM technology for Sustainability from a construction standpoint is limited. The primary efforts for a sustainable project during the construction phase are concerned with producing all required documentation for LEED certification. It would be more accurate to describe this portion of the process as Information Modeling rather than Building Information Modeling.
Methods of take-off have also been implemented into the construction phase of a project in order to track the amount of sustainable materials that are being utilized throughout the project. Programs can easily calculate the content of recycled materials, certified wood, regional materials, etc. needed for LEED credits in a matter of minutes.
Operation
A sustainable project limits its impact on both the current and future environments. It is therefore necessary for the performance of the building's systems to be monitored over time by means of a Building Performance Analysis. These analyses can evaluate a system and see if it is functioning as it was originally intended as well as identify problematic areas that require repair or redesign.
Potential Benefits:
[_] Acceleration of the design review and LEED certification process with efficient use of a single database with all the sustainable features present and archived
[_] Improved communication between project participants in order to achieve LEED credits and decreased redesign efforts as a result
[_] One central database is developed incorporated with various engineering analyses' information that can serve many purposes
[_] Owners, designers and end users are able to visualize and understand better the impact of their building on the environment time before it is built streamlining the design process
[_] Aligning scheduling and material quantities tracking for more efficient material use and better cash flow analysis
[_] Portfolio management enabled for owners with similar projects allowing them to reuse models and standardize their design and construction to save on material use and cost
[_] Building performance can be optimized by tracking energy use, indoor air quality and space planning for the adherence to LEED standards leading to integrated facility management using a BIM model
[_] Designers adopting BIM are more likely to adopt green technologies as well like energy and resource efficiency, alternative energy development, advance material use, information management, and environmental/health (Boutwell, 2008).
Levels of Detail Considerations:
The level of detail depends on the sustainable features the BIM model is used for: site selection, spatial planning, daylighting, energy modeling, material tracking, etc.Please see the BIM use pages referenced in the descriptions above for detail considerations.

Potential Modeling Methods:
The potential modeling methods depend on the sustainable feature the BIM model is used for and what kind of analyses or data tracking needs to be done. Please see the BIM use pages referenced in the descriptions above for detail considerations.
Potential Outputs:
BIM model provides a database of all the sustainable features that can be used for LEED certification and various planning and sustainable information tracking throughout the project phases.
Legal / Commitment Considerations:
Areas for legal consideration include business agreements and liabilities associated with the transfer of the modeled information between the parties of the project. The use of BIM for sustainability relies heavily on a database that can be shared between all parties on a project, i.e. developers, architects, engineers, contractors, etc. When one party has finished their use with the model, risk is associated when the model is transferred to the next party. For example, when an engineer completes his energy analysis, the model may be passed to the contractor for material tracking for LEED credits, the information passed may be altered, inaccurate or lost, thus putting the contractor at a disadvantage and likelihood for error.
